"ttywatch" (it's in fedora-extras) is what I use for serial console monitoring. It logs stuff permanently in the background, with proper log file rotation; but it also lets you connect to the console live, via a per-port telnet-to-serial relay, when you need it. And it passes ^A through just fine. btw, for FC5 xen builds, it turns out that serial console input (which is needed for the HV to see the ^A's) doesn't work unless you specify pnpacpi=off on the kernel boot line. We need to work out why: I suspect that the ACPI pnp bios is tweaking the serial lines for mouse probing and is upsetting the HV console input in the process. --Stephen
